Electrical Hazard:
Warning that failure to observe the pre-
caution may cause electric shock
WARNING:
Warning that failure to observe the pre-
caution may cause personal injury or
damage to property.
In addition to these operating instructions please
pay attention to universal safety and accident
prevention regulations.
Basically the HYDROVAR must be disconnected
from the power supply before any work can be car-
ried out on the electrical or mechanical part of the
system.
Installation, maintenance and repair work may be
carried out only by trained, skilled and qualified per-
sonnel.
Unauthorized modification or changes to the system
make all guarantees null and void.
During operation, the motor can be stopped by
opening a digital input or manual operation whereby
the HYDROVAR and the motor remain under volt-
age. For safety reasons, the HYDROVAR has to be
disconnected from the power supply when carrying
out work on the machinery.
Electrical Hazard:
When the HYDROVAR is connected to
the power supply, the components of the
power unit as well as certain compo-
nents of the control unit are connected
directly to mains.
Touching these components seriously
endangers life!
Before removing the HYDROVAR cover
the system must be disconnected from
the power supply. After switching off the
power supply wait at least 5 minutes
before starting work on or in the HY-
DROVAR (the capacitors in the inter-
mediate circuit are discharged by the in-
ternal discharge resistors).
Voltages of up to 800 volts are possi-
ble (in case of error these also can be
higher)
All work, carried out on the HYDROVAR,
may only be performed by qualified and
authorized staff.
Furthermore, take care not to short cir-
cuit the neighboring components when
connecting the external control wires. All
cable ends which are not in use have to
be isolated.
WARNING:
The HYDROVAR contains electronic
safety devices which switch off the con-
trol element in the event of a fault,
whereby the motor has zero current but
remains energised and comes to a halt.
The motor can also be halted by me-
chanical blocking. If it is switched off
electronically the motor is current less
from the mains voltage through the elec-
tronics of the HYDROVAR but is not po-
tential-free in the circuit.
In addition voltage fluctuations, especial-
ly power failures can cause the system
to switch itself off.
Repair of faults can cause the motor
to start up again automatically!
WARNING:
The system may only be put into opera-
tion when it has been grounded.
In addition to that, equipotential bonding
of all conductive pipes must be ensured.
Please consider local installation stand-
ards!
Electrical Hazard:
Do not do voltage withstand on the AC
drive. The manufacturer has already
done the test. Doing voltage withstand
test can cause damage to the drive.
NOTICE:
The operating instructions must be read, understood
and followed by the operating personnel. We point
out that we accept no liability for damage and oper-
ating disorders which are the result of non-compli-
ance with the operating instructions.
